Weather-cock

By a Papal enactment made in the middle of the ninth century,
the figure of a cock was set up on every church-steeple as the emblem
of St. Peter. The emblem is in allusion to his denial of our Lord
thrice before the cock crew twice. On the second crowing of the cock
the warning of his Master flashed across his memory, and the repentant
apostle “went out and wept bitterly.”
